Robert Downey Jr. has invited a 7-year-old boy named Daniel, who’s suffering from cystic fibrosis, to be his guest at the 2016 premiere of Captain America: Civil War. Downey sent out the invite via his Instagram account, and dressed up in a Tigger costume to do so. See photo below!

The sick boy’s mother Vicky explained her ailing son’s situation in an Instagram post. She wrote, “[He] wants nothing more to meet his idol Robert Downey Jr (aka iron man) as he has managed to get past the bullies he faces from day to day by telling them the he too has a extra special port in his chest much like iron man has his arc reactor.” She added, “I hope that it could help him through his stay in hospital as it is starting to take its toll on him.” Cystic fibrosis is a life-threatening disorder in which thick mucus builds up in the lungs and other vital organs.

Downey Jr. received the message a few days later, and wrote to the boy on Instagram, “When I’m in the dumps, I’ve found this little getup to be helpful,” referencing the photo of him wearing a Tigger costume.” The star added, “P.S. Would you like to come to the LA premiere of Captain America: Civil War as my guest? If so, have your people call my people. All the best.”

As Gossip Cop reported, a video went viral last year of Downey Jr. presenting a real-life bionic Iron Man arm to a 7-year-old boy who was born with a partially developed limb.

The upcoming Captain America sequel opens on May 6, 2016, and the film’s premiere will be held shortly before. Check out Downey Jr.’s photo and message to his young fan below, and tell Gossip Cop what you think.
